Dear Community,
I have a question regarding the upcoming setup of my storage pool that so far I wasn't able to answer despite having read a bunch of threads, blogs and the famous slideshow. (Yes, I learned drives make up VDevs, Vdevs, make up pools, and that where you save your stuff...
I have 4x4TB drives that I would like to arrange in a RAID1 type setup. The idea: 8 TB net storage space, 8TB as mirror of that, one drive can fail. If it does fail, I simply want to replace it and the show goes on.
How Do I Do That? Is it
1.) two drives mirrored in a Vdev, and the other two drives in a second Vdev and together those 2 Vdevs form the storage pool? or
2.) two drives striped together in a Vdev, and the other two drives striped together in a second Vdevs, and together those 2 Vdevs form the storage pool?
(I know there is stuff like RAID1z and RAID2z but I don't see any real advantage of that - I must have an offline, off-site backup anyways.)
Thanks for your help!
